Depending on the driving distance. I would either drive to personally see my relative, talk about specifics for each firearm and pick up the guns and bring them back. Then list here and / or Texas Gun Trader. I'm sure the relative would expect some compensation such as a free gun or a small percentage of the take. If driving is impossible, and it sounds like a large and expensive collection. Using a freight company for delivery might work as well.

It is 100% illegal to transfer handguns across State lines without an FFL in the middle. That includes giving them to relatives.
There are exceptions for inherited firearms and in some cases exceptions for long guns.

Somewhere like Collectors Firearms would buy the entire lot in one transaction with payment in full at the time. Yes, it would be a discounted amount but they would take care of everything including getting them back etc..

It's fine if you disagree. I can't force you to be correct.

A pistol without a round chambered is an expensive paper weight.

• Give me Liberty or I'll get up and get it myself.
• I don't carry because of the odds, I carry because of the stakes.
• My dream is to have lived my life so well that future generations of leftists will demand my name be removed from buildings.
• Independent Minarchist.

The OP has gotten some pretty good assistance in his corner at this point. It will be interesting to read about how it all shakes out.

I can see where one might have concerns over selling 100's of firearms in this day and age. Naturally using an FFL for all transactions helps. From what I understand on the selling of firearms is one can find themselves being accused of operating as a firearms dealer without having the proper licensing.

Maybe one of the FFL's on the forum can chirp in but I was warned by a few on this very forum that all my buying and selling of firearms on gun broker may start looking bad. I was nowhere close to selling a hundred firearms. I was simply trying to improve my personal collection.

I would recommend he put them on consignment at a local gun shop that sells used guns.

So as a general thing, it looks like a .36 caliber cap and ball 6-shooter handgun manufactured in 1865 would still be subject to all of the same transfer/shipping laws as a modern handgun .... while a far more powerful magazine fed Krag Jergensen battle rifle manufactured before 1889 would not be subject to those restrictions. I guess that makes some kind of sense on Planet Bizzaro.

Until some person walks into a gun free zone with a couple 50 caliber muzzle loaders and kills a few people. Then the leftist regime will call for outlawing those as well.
